1'0 all 'uhh/mt it may (roll/cern.

Be it known that I, IVILLIAM I. Knnsn, a citizen of the United States,residing` at Chapinan, in the county of Rankin and State of Mississippi,have invented certain new and useful Improvements in Churn OperatingtIechanisns, of which the following is a specification. i..

This invention aims to provide a ovel mechanism for operatingchurn-flashers of the type receiving a reciprocating movement andcombines with said mechanism a fan for creating a current of air forcooling the surrounding atmosphere, so as to be of advanboth to theoperator and to the churning operation. y

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

Thile the invention may be adapted to different forms and conditions bychanges lin the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying' drawings, in which- Figure l is a perspectiveview of a churn embodying the invention, the receptacle for holding thecream being omitted. Fig. 2 is a transverse section of the operatingmechanism, showing the gearing in full lines. Fig. 3 is a verticallongitudinal section of the upper' portion of the frame, showing thegearing in full. v

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the sainereference characters.

The framework of the churn comprises uprights or corner-posts l, aplatform 2, and upper longitudinal and transverse bars connecting theupper portions of the uprights or corner-posts l, so as to provide asubstantial structure. The receptacle (not shown) for containing thecreamto be churned is supported upon the platform 2, and the dasher 8 isadapted to operate therein by a reciprocating movement. An operating rodor bar Ll has its lower end offset or bent at about a right angle, asshown at 5, and clamped or otherwise secured to the dasher-shaft. Theoperating rod or bar 4 is mounted so as to receive a reciprocatingrectilineal movement and is 'provided intermediate of its ends with ahorizontal arm (5, which is slotted to receive the crank portion 7 ofshaft S, mounted at its ends in bearings applied to longitudinal bars ofthe framework. Any suitable means may be employed for securing theoperating rod or bar to the framework and directing it in itsreciprocating movements. As shown, the upper portion of the rod or bar 4is provided with a vertical slot 9 to receive a headed pin or fasteningl0, and a screw-eye ll or like confining means eoperates with the lowerportion of said rod or bar l below the slotted arm 6. By having thehorizontal arm 6 arranged between the upper and lower guide means forthe operating rod or bar the latter is prevented from binding, and thestrain is about equalized upon said guide and confining means.

rI`he shaft S is provided with a pinion l2 and is in mesh with agear-wheel 13, fast upon a drive-shaft 14, mounted in bearings appliedto the upper longitudinal bars of the framework. The drive-shaft 14 andthe crankhandle l being in parallel relation, the driveshaft 14 isadapted to be actuated by suitable power, and in the event of themechanism being designed for manual operation a crankhandle l5 is fittedto or formed with an end shaft of the drive-shaft 14. A fan 16 is fastto the crank-shaft 8, so as to rotate therewith, and may be of anyconstruction.

The milk or cream to be ehurned is placed in a vessel or suitablereceptacle in the accustomed way, after which the dasher is placed insaid vessel and the latter arranged upon the platform 2, the dasherbeing attached at its upper end of the operating rod or bar 4. Uponoperating the drive-shaft 14 by means ofthe crank-handle or in anydeterminate way motion is imparted to the crank-shaft 8 by means of thegearing, the dasher in turn having a vertical reciprocal fmovementimparted thereto by the action of the crank 7 operating in the slot ofthe arm 6. Simultaneously with the churning operation a circulation ofair is created by the action of the fan, which is both cooling andserves to drive away insects and carry off noxious odors, as will bereadily oomprehended.

Having thus described the invention, what is claimed as new is- Incombination, a framework, a shaft journaled thereto and having a crankportion7 a fanand a pinion secured to said shaft upon opposite sides ofthe crank portion thereof, a
